Description

`valarray` public member functions

explicit valarray(const context & context = system::default_context());

explicit valarray(size_t size, 
                  const context & context = system::default_context());

valarray(const T & value, size_t size, 
         const context & context = system::default_context());

valarray(const T * values, size_t size, 
         const context & context = system::default_context());

```
valarray(const valarray< T > & other);
```

valarray(const std::valarray< T > & valarray, 
         const context & context = system::default_context());

valarray< T > & operator=(const valarray< T > & other);

valarray< T > & operator=(const std::valarray< T > & valarray);

```
valarray< T > & operator*=(const T &);
```
```
valarray< T > & operator/=(const T &);
```

valarray< T > & operator%=(const T & val);

```
valarray< T > operator+() const;
```
```
valarray< T > operator-() const;
```
```
valarray< T > operator~() const;
```
```
valarray< char > operator!() const;
```
In OpenCL there cannot be memory buffer with bool type, for this reason return type is valarray<char> instead of valarray<bool>. 1 means true, 0 means false.
```
valarray< T > & operator+=(const T &);
```
```
valarray< T > & operator-=(const T &);
```
```
valarray< T > & operator^=(const T &);
```
```
valarray< T > & operator&=(const T &);
```
```
valarray< T > & operator|=(const T &);
```
```
valarray< T > & operator<<=(const T &);
```
```
valarray< T > & operator>>=(const T &);
```

valarray< T > & operator*=(const valarray< T > &);

valarray< T > & operator/=(const valarray< T > &);

valarray< T > & operator%=(const valarray< T > &);

valarray< T > & operator+=(const valarray< T > &);

valarray< T > & operator-=(const valarray< T > &);

valarray< T > & operator^=(const valarray< T > &);

valarray< T > & operator&=(const valarray< T > &);

valarray< T > & operator|=(const valarray< T > &);

valarray< T > & operator<<=(const valarray< T > &);

valarray< T > & operator>>=(const valarray< T > &);

```
~valarray();
```
```
size_t size() const;
```

void resize(size_t size, T value = T());

```
unspecified operator[](size_t index);
```

unspecified operator[](size_t index) const;

```
T() min() const;
```
```
T() max() const;
```
```
T sum() const;
```

template<typename UnaryFunction> 
  valarray< T > apply(UnaryFunction function) const;

```
const buffer & get_buffer() const;
```

`valarray` private member functions

```
